FLUXING ATTACHMAENT FOR SEAMIYNG-MACHINES.

SPECIFICATION forming part of Letters Patent No. 525,625, dated September 4, 1894. Application nea iugm 23,1893. semina. 483.817. (Nomade.)

To all whom t may concern.-

Be it known that I, HENRY SOHAAKE, a citizen of the United States, residing at San Francisco, 1n the county of San Francisco and State of California,have invented certain new and useful Improvements in Fluxing Attachments for Seaming-Machines; and I do hereby declare the following to be a full, clear, and exact description of said invention, such as will enable others skilled in the art toV which it most nearly appertains to make, use, and practlce the same.

This invention relates to a certain new and useful iluxing attachment for soldering or seaming machines, more especially to that class designed for the seaming of can bodies,-

and it consists in the arrangement of parts and details of construction as will be hereinafter more fully set forth in the drawings, described and pointed out in the specification.

The obJect of the present invention is to permit the flux to be supplied to the metal after the bodyof the can has been formed, but prior to the soldering thereof, so as to insure against the flux being displaced, which does occur where the linx is applied to the sheet metal previous to its being formed into the shape required; to provide Yfor the flux beingevenly and uniformly applied to the metal or unsoldered can body ;l and to so supply the flux as to prevent the same making its appearance upon the inside of the can body when finished.

Referring to the drawings forming a part of this application- Figure l, is a top plan view showing the uxing device attached to a seaming machine; Fig. 2, a front elevation of Fig. l. Fig. 3, is an enlarged detail top plan view of the Iiuxing device; Fig. 4, a side elevation of Fig. 3. Fig. 5, is a front elevation of the flux-brush and hollow feed frame, the guide bar being in cross section, taken on line -/.c- Fig. 3. Fig. 6, is an enlarged detail viewv of the flux brush and feed supply therefor; Fig. 7,- detail top plan of the perforated brush holder, and Fig. 8, is a detail view of the operating cam.

The letter A, indicates the base or frame of an ordinary can body seaming machine, A the mandrel thereof, and A2 the clamping jaws for forming the sheet metal blank into a can body over the mandrel. The vertical operating shaft B, is maintained in position by the arms B', and rotary :motion is imparted to said shaft through the medium of cross shaft B2, which is operated by means'of shaft B3, by the gear wheel b, intermeshing with gear wheelb. All of these features and their workings being well known 'and forming no part of my invention, call for no specific description herein.

To the upper portion of the rotatable shaft B, is movably secured the sleeve C, from which radially projects the guide arm or rod C', through the outer portion of which is cut the slot c, the upper portion of said slot being enlarged as shown at c2, within which enlarged portion fits the wedge-shaped sliding block C2. Through this block extends the stem C2, of the feed frame C4, which has a forward and backward motion within the slotted portion c, of guide arm C', being carried by the movement of the sliding block C2. The feed frame has a vertical movement by means of the vspring D, which surrounds the stem C3, and

is secured between the collars d, d', as shown. From the sliding block C2, projects the pin d2, whichfcarries the roll D. within the groove D2, cut or 'formed in the under face of the bar or plate D3. This plate is fastened to the arms E, E', one of which is shorter than the other, see Fig. 8, consequently the plate D3, runs at an angle to the frame of the machine. Asthe roll D', travels within the groove D2, the sliding block is drawn or moved inward toward the vertical shaft B, and carries the feed frame therewith.

To the seamer, at any convenientpoint, is secured the flux receptacle or chamber E, whichcontains a liquid flux, and said chamber is'connected to the stem C3, of the feed frame C4, by means of the flexible pipe or hose E. The liquid flux is thus conveyed from the chamber to the stem, whence itv enters into passage-way e, of the stem and feed frame and is finally dischargedupon the' perforated top plate of the brush holder.

ATo the feed frame is secured the brush holder E2, which is perforated so as to permit the liquid AIiux to flow upon the bristles F, se-

cured within the holder, as shown. These bristles'constitute the brush for applying the iiuxto the can body.

An oscillating motion is imparted to the This roll worksv ing from the rod F3, which is connected at itsf upper end with link f2, said link in turn being connected with one arm of the crank lever E3, the other arm of said lever being connected to arm C by the rod E4.

As the rod F3, which works through the bracket F4, is raised,rarm Z of the crank lever is thrown inward which causes the guide arm C', through the medium of the connecting rod E4, to rnove likewise, but in unison with` the travel ot' the seaming mandrels. As the arm C', is carried around, the roll D', of the sliding block C2, is caused to travel within the groove at an incline, and it is obvious that the travel of the roll D', within the groove gradually draws the sliding block inward toward the vertical shaft B, which carrying the feed frame therewith, causes the brush to move over the seam of the can body, held between the clamp jaws, and deposits the iuX thereon. The brush is brought into contact with the can body by means of the roll h, secured to one side of the feed frame, working upon the inclined face lh', of track h2, secured to the under face of arm C. The arm C', continues its rotary travel until the brush has moved its full inward distance toward the vertical shaft B, which carries the iuxing brush beyond the edge of the can body, when the eccentric cam will be in such a position 'as to impart a quick downward movement to the rod F3, which reverses the motion of the arm C', and forces the slidingblock toward the outer end of the arm, thus carrying the tluxing brush outward or away from the vertical shaft B. It will thus be observed that the said brush is carried in or out, the outward movement being somewhat quicker than the inner one, in order to place the brush'in position to apply the flux to the next can body.

The fluxing brush when moved its full outward distance is held away or out of contact with the can body by the action of the spring D, but when the arm C starts to rotate with the shaft B, the roll 71, engages with the inclined face h', of track h2, and as the arm C continues its movement the roll h working upon the inclined face h', causes the brush holder to move downward until the ux brush contacts with the can' body and theV same is held firmly against the body until by its inward movement the brush has traveled over the entire length of the can body seam. .O f course as the brush holder is moved downward in order to cause the brush to bear upon lthe can body, the spring D is compressedmV As the sliding block moves its full outward distance or away from the vertical shaft `B, the roll h moves from o'the inclined face 11,

of the track 722, and the resiliency of spring This cam has a groove f, cut therein,

D,'raises the `feed frame and-brush above the level otV the can body so as toclear the edge of the can body held between the next set of clamps, in order that the flux may not scraped off the brush, which would result did the brush on its outward movement contact with the edge of the can body.

It will thus be noticed that by the use of this device the iiux is placed upon the metal uniformly, and in such a manner as not to run on the under surface thereof.

Having thus described my invention, what I claim as new, and desire to secure protection.
